Brie,
If you are a "set and forget" listener then I want to throw you another suggestion, Basis Vector. This arm does not have dials and such so setting it up is a bit more work. However, once set this arm never needs re-adjusting. The Vector is very well engineered and can handle just about any cartridge you want to mount on it. That's not to say the Tri-Planar or SME can't also but the Vector is alot less money. Because it is a modified unipivot you will probably never have to worry about maintenance. I think it would be a good match with the Avid as it can hold the arm very stable.
You could also start with a Denon 103R cartridge and save more money towards that next higher end cartridge, but I do like the Glider.
