Buy a Lenco L75 or similar, if you can use a jigsaw make a plywood plinth for it. Remove the stock arm and a Linn geometry arm (Linn, Pro-ject, Hadcock etc) fits into the standard arm-hole. If you don't want to make a plinth you can probably buy one from ebay. The Lenco will probably need re-oiling but you won't have to touch it for years. Upgrading the ball in the main bearing to silicone makes a further upgrade.
