Well, my Baja has got Blackguard Flat 50s in it - that's what I'd go for personally, but I might be tempted to enquire (Tim/BKP) about these Blackguard 52s that Philking mentions - I wouldn't mind knowing what they're all about.
I kept my Baja stock for 2-3 months, and was struggling to "get into it". The minute I put the Blackguard 50s in it was the business for me - everything just a little bit fatter/warmer than the stock pickups but still with all the clarity/top-end.
I've not played a real Broadcaster/Nocaster, but this thing sounds fairly "authentic early tele" to me.
I use it for blues/rock/country type noodlings, and depending on the amp models I use I can get it to do biting tele or fat tele, sounds great clean, dirty.... everything I want :D
