Yeah, well, I saw that $200 budget detail last.
For $200, you're best value is in the Ebay market. You could easily afford some of the best model numbers for that much, depending on the day. I see bids go high and low, every day, but you're easily within reach of a used:
424mkIII
424mkII
414mkII
244
246
464
644
Porta One
Porta Two(& HS)
The 424mkII, 464, Porta One and 244 often bid in the $100 range. The 414mkII, Porta Two & 246 often bids in the $150 range. The 424mkIII often bids in the $200 range.
You don't have much buying power for $200 in brand new recording gear. That gets you a Porta 02mkII and a mic at Guitar Center. The right Ebay gear buy could be a huge gain in value over brand new equipment.
Honestly, analog's gone to a mostly used market, because remaining stocks of new analog multitrackers are so limited, they're almost gone completely.
For under $200, IMO your best value is the Tascam 246, given that you can find a pampered low use unit. For less than $200, depending on the day, with a VG-condition 246 you'd be really stylin'.
The 244 and 424mkII are also a great value in their price range.
The 464 is a topline model that's apparently a bit less popular, and therefore it may often be had at a steal of a bargain price. A 464 bidding in the $125 range would be a tremendous value.
I tend to recommend the 464 and 644 a bit less, because they're increasingly more gadgety than most of the other Tascam Portastudios. The 464 I could handle, but it has a menu driven assign function and LCD meter. The 644 is very gadgety indeed, with built in midi synchronizer, and tons of buttons, that's also equipped with a digital LCD assign matrix and VU level meter bars.
Anyway, all those models are out there. Shop Ebay/Tascam for a while, and make up your own mind. All the models I've mentioned are worthy multitrackers, in their own right.
Good luck.
