Is this product any good, or can someone recommend a good one for less than $600?

I agree, Research and learn first. As a means of comparison, a basic Sherline Lathe starts at $624, plus shipping from CA. You should probably figure another $300-400 for accessories needed for any serious work.
The block plane comment referred to shaping of wooden spars by tapering square stock, planing 8 sided, then sanding round. A good way to make wooden spars.
