Aaron,
How about a saw replacement/upgrade for $275. Seriously this is a great price and an upgrade from what you have. (Not a Unisaw, but not a Uni price either!) You could sell your current for $75 and upgrade for very little $$

Enjoy the hobby. It gives me much fulfillment and fun, I hope you enjoy it too and take all the "advice" given here with the positive flavor it was meant.
