The Gossen Digisix meter has a 25-degree incident reading plus the ambient reading. Didn't you want something more narrow?
I dont know what I want, im processing all of this and I appreciate yours and everyones input very much! Thank you.
If you haven't worked with a spot meter and something like the Zone system before, I'd suggest that something like the non-spot choices recommended are a better place to start.
I consider spot meters to be a specialized tool, and for most of my efforts prefer something less specialized.
I make a lot of use of the incident light metering capabilities of my hand held meters.
Gossen Variosix F and F2 are rarely mentioned and pretty affordable used. There is a 5 degrees spot attachment.
By modern standards they're pretty bulky, unless you're working with a lot of gear and one more piece doesn't make any difference.
I have too many meters, and my most used is Sekonic L-308B both outdoors and indoors (flash). It is just the right size, function and ergonomics for me. I have smaller ones (Gossen Digisix), more low-light sensitive ones (Gossen LunaPro SBC), and more versatile ones (Sekonic L-558R), but none of them gets more use than the L-308.
I also have two defunct Gossen Luna Pro SBCs. Therein lies the problem - no one in N. Am. or elsewhere will repair "legacy" Gossens,
I want the kind that i point at the subject. A spot meter would be great.
I can recommend the Gossen Lunasix 3. A battery adapter to replace the mercury cells is available from Gossen directly.
Small, lightweight and even cheaper is the Gossen Sixtino (Selen cell). My go-to meter for outdor use with the Canon 7, Rolleicord or Adox Golf.

I did not realize they sold a shoe adapter for the Digisix. I found this picture on the internet. Looks nice, I might have to get one to add to my collection of small meters.
The forward voltage drop of a small signal shottky like the BAT85 is around 0.21V at the very low current drain of an exposure metre, and a silver oxide cell yields 1.55V, thus the resulting voltage of the concoction is 1.34V. I compared the readings with that of my minolta spotmeter F and they match well beyond my ability to proper aim the arrow on the lunasix dial.
The zinc-air cells provide 1.35V and, again, when checking against my minolta I couldn't find reading differences.
The CdS remark is solid though, silicon cells are more durable. The lunasix sell for quite lower prices wrt other metres though, possibly because of the pesky power supply.
Zinc air or Silver Oxide can't hold the output voltage to within 1% for 95% of their useful life like Mercury Oxide.
I should mention that this is not quite accurate statement - the forward voltage drop on any diode, Schottky or plain, is not fixed - it can be 0.21V only for certain current flowing through it (let alone only at certain temperature), e.g. this voltage is highly current dependent. In case of usage in Luna Pro - meaning this drop will be different depending on which scale you're taking the reading at: the meter draws ~10...300uA on low scale, ~50...500uA on high scale and ~200uA during "Batt Check". So the diode voltage drop will vary depending on what you're doing; the diode will not only introduce non-linearity, but inconsistent one. Small, but noticeable. For most users it's just small enough not to matter, but it's there. The right way to deal with this is to make a proper voltage regulator with fixed 2.7V output.
