I am a die-hard Pentaxian, and the ME Super is one of my favorite walk-around cameras, but as someone else said... for manual mode, it's not great. The buttons are a slow way to set shutter speed, and the meter display only shows the selected shutter speed and an OVER or UNDER indication. It doesn't show recommended speed, and there's no way to know if you're half a stop off or ten stops off. Can you get the right exposure with a single click of the aperture ring, or do you need to speed up your shutter by a few stops? No easy way to tell with the ME Super.
In my assessment -- and keep in mind, I really do love this camera -- it's more of an automatic camera with a manual mode than a manual camera with an automatic mode.
Unfortunately, in my opinion, Pentax doesn't make a good dual-use manual/auto camera (like the K2) in the M-series. The MX is manual only, and it's light, but I've never loved mine -- I find the shutter speed dial stiff and difficult to turn, and I don't care for its LED display, which is basically a glorified center-the-meter system like on the K1000. Being mechanical, it may well be gummed up and need a CLA.
The K2 is better, with a proper match-needle system, but it's a K-series so, like the K1000, it weighs as much as a small automobile.
The Pentax P30T is a nice camera for manual/auto use; it has the electronic version of a match-needle display, showing both selected and recommended shutter speeds. BUT -- it only sets film speed through the DX code (so no good for us bulk-loaders, unless you have DX stickers on your canisters) and it doesn't do super-long exposures in auto mode like the M-series cameras.
I've found the best compromise is Ricoh. They used polycarbonate bodies (years before Canon did!) and size- and weight-wise the models I like best (more on which in a sec) come midway between the K- and M-series Pentax bodies. They are 100% compatible with Pentax lenses but the Rikenon lenses are good too, and lighter to boot.
My fave is the XR-2s, which has manual/auto, DOF preview, mirror lock up w/ the self timer, and aperture "judas window" like the KX and MX. More importantly it has a proper match-needle meter and a proper shutter dial. KR-10 (*not* KR-10M or KR-10 Super) is similar but lacks a few features. (Not sure if they will do mega-long exposures; haven't tried.) Not as refined as a Pentax but they're inexpensive, more so if you buy the Sears-branded version (XR-2s is Sears KS Auto, KR-10 is KSX). I don't think I've ever paid more than $20 for a Sears camera; Ricoh branding might double that.
KR-10 Super (Sears KSX Super) is lighter still -- about the same weight as an ME Super. But it has an LCD meter that I find hard to read in the dark and a hair-trigger shutter release. I don't like it as much as my other Ricoh/Sears cameras.
