I know a ton of folks, including myself, that have the "$179" model available everywhere...Harbor Freight, etc...they are inexpensive, work great for the price and don't take up a ton of room in your shop. They have 64 1/2" x 1/2" blades you can get from anywhere as well. That is about your only real option if you want to stay in that price range.
Have a great one,
Hank
