Take 4yanx's advice. I've never heard either of the tables myself, but I'd choose the Nott' over the Linn any day. It's just a better design all the way around.
The Innerspace comes with a Rega arm, right? If so then any of the cartridges recommended by Sbank would be excellent. The superb Shelter 501MkII is $100 over your budget. If that's too much then the Denon 103R is a very close second best, and a steal at <$300. Note that either of these cartridges will need a high gain phono stage or a stepup device. If THAT blows the budget or presents other problems, go with the 10x5.
