Don't limit yourself to just these three tables. I would seriously consider the advice of Art Salvatore (www.high-endaudio.com). For the price point you are in, you can get a VPI Hw 19 Mk. IV used for a good price. There's a Mk. III on sale now for $585. You could call VPI and get another armboard for $100.
With the rest of the money, you could get a good tonearm/cartridge combination. I would look at the Denon 103 (requires 61 db gain in phonostage), Shelter 501 Mk. IV (also requires about 57 db gain), Clearaudio Wood Beta, or a Dynavector 10x5 (if you can and have over 62 db gain, go for a used 17D).
There was even a Aries on here for $1400 with a RB arm board. You could have done that and went to www.britaudio.com and got an Moth Oem Arm 2 (OEM RB 300) for $275. That, minus cart, would be the range of the Scout and the Aries would CREAM the Scout.
My point is to look around in the used market. The Absolute Sound, Audioasylum.com, Audiogon.com, SoundStage (vinyl column), Stereophile (Recommended Compontents) can help you in your decisions. For me, Arthur Salvatore's web blog (www.high-endaudio.com) is the definitive voice for good used audio.
thoughts anyone?
