That Tascam is a nice unit but doesn't include a cd burner, so you'd have to burn off of a pc. Tascam is good quality, but your recordings will depend on you. You can spend $10,000 and still sound like crap if you don't know what you're doing. Or, you can make a fairly decent quality recording with that Tascam unit, if you do know what you're doing.
Boss makes a couple units around that price range as well. You can also probably find some used highrer end units around that price as well.
