I am surely in the "prosumer" league here, so take my comments in that spirit. I have a Tascam 38, and like it a lot. I also have an Otari MX5050BII-2 as a mixdown deck. I like the features (switchable operating level and eq, front panel bias adjust etc. ) On paper, it's a great machine, nothing compares to it for shear flexibility.
In practice, the reel hubs are crap, they don't lock down very well, and I have to lay it on its back, to avoid reels wobbling themselves loose. The tape path has no tolerance. 1/4" is what 6.35mm? I think the guides are exactly that, any slight tape width variation (which is like saying any chance of rain in London or Seattle) and I have oxide all over the place. Don't get me wrong, I'm keeping the Otari, I like the Otari, but I hate it too.
The 38 may be "entry level" (not sure why that is) but it *sounds* great, has three heads, and analog VU's on the front panel. Yeah, I did need to get the dbx units separate. But I can't think of any other feature I'd really need, the MSR-16 will record at 7.5ips. I can't imagine doing so. Either machine has its strengths and weaknesses. The *flexibility* of the Otari is awesome, three tape levels, two EQ settings, bias adjust, two track playback/record, and four track playback. Three speeds. OTOH, the brutal simplicity of the 38. No complicated permutations, one speed, record, sync, playback.
Consider the features you need vs the nice to have, I'd advise get the best deal on the machines in the best shape, and don't worry so much about brand. BTW, $2500 does seem way way high, unless we're talking new heads and a recap.
