As for upgrading the pups, I am thinking about putting in a set of Keystones! Not that much more than toneriders and by all accounts they are amazing...
If you're referring to Bill Lawrence Keystone pickups, they are supposed to be very good, but with the current exchange rate and international postage they're about $212AU. The Tonerider sets from PBG are $119 (free postage). I've used the TR Tele pickups and they're very good sounding pickups, especially for the price.

Also, Wilde Pickups (Bill Lawrence) advertise shipping within 2 weeks of ordering (they build to order) but I know people that waited over 2 months with no status updates along the way. Best case would be 4 weeks with production and shipping time, but given the current crisis (particularly in the US) who knows...
I personally cancelled an order in 2015 after waiting 5 weeks with no email replies. They are literally an old fashioned US "Mom & Pop" business (now a Mom & Daughter operation since Bill's passing) so I get it, but I wasn't willing to keep waiting and was annoyed that no one replied to any of my emails (except confirming my order was cancelled).

I'm not saying don't buy them or that they're no good, just thought you should know what you could be getting into.

FWIW, one forum friends that waited 12 weeks, said they were worth the wait. However, patience is not always one of my strongest attributes .
