Depends on how far you want to stray from the traditonal Tele tone.
The Suhr Tele pickup set is great, and covers a lot of bases.
My favorite set, as of late, is the Duncan Jerry Donahue bridge pickup, with the Dimarzio Twang King neck pickup. Super versatile, fat bridge, clear neck. The JD has more midrange push, and less top end slice, than a normal Tele pickup, but can still twang. I think it's damn near perfect.
On a budget? Get a used Duncan Broadcaster. A steal at $40 bucks.
