I've got the 208 and a minolta flashmeter V.
208 is light, small, the long lasting lithium button cell is the most popular there is and can be bought at any walmart, stolen from dead computers and most illuminated junk toys from china. The flash shoe attachment is junk, but it is very easy to wear around the neck or put in your pocket. Its fashionably accompanies a TLR or press 4x5 anyday.
The flashmeterV works in super low light, fires and measures flash illumination, can average multiple readings, digital backlit display, etc.. It runs for years on a single AA. If money were no object, I would get a flashmeterVI to gain easy spotmetering. The V is big enough to not easily go into pockets, meaning you pretty much wear it around your neck. With it's buttons and LCD it's more professional looking than a 208 which is sort of quaint and classy. It comes with a nice padded case for transport/storage/protection.
