I'd second Luke's opinion on the Consew , especially if it's one of the old Japanese made machines- I have an old 206 RB and a 105 - they're great. I also have a Sailrite knock-off, but with the same motor, and it's just not strong enough for almost anything I do, and the stitch length doesn't stay consistent when you sew thicker material.
I think Sailrites are overpriced - I'd go for a table machine if I were you, and don't worry about the speed, you will learn how to sew slowly with a bit of practice, and you can later buy a Servo motor for around 300 bucks, to reduce the speed, and you'll still be cheaper than the Sailrite
Weaver's price for 3/4oz suede is 1.78 a foot and $1.67 for 2/3oz once you get your tax number
