Even if you are talking about only the table itself, no arm or cart, I can't think of any choices in your price range. Possibly an older model from Oracle, but again, in that price range? If you want an arm and cartridge as well for that $300, forget it, not going to happen, I don't think. There aren't really a lot of table manufacturers who design tables to be upgraded in the first place, and the ones that are, start way above your budget normally. The best example I can think of would be the VPI Scout, but their starting price is multiples of your budget even used. The good thing about buying a table in your price range, even if you can't upgrade it is that if you do decide to upgrade in the future you should be able to recoup the bulk of your initial investment when selling the table. This would be much different than say spending $1500 to $2000 for a table that can't be upgraded, and then wanting to move up later.
