Strings and pickguards are easy to replace. Please don't be afraid of a string swap. If the bass is difficult to play, take another run at the setup using the directions in the Hardware forum.
I have a Bronco with a replacement pickup (I bought it to experiment with) and it's a very playable, well balanced bass. Not sure what people think the problem is with them.
I've had a Squier Jag and found it very playable; I sold it to a friend who plays it a lot.
If you want good sound in a short scale at a low price, check the Gretsch 2220. Short scale, 3 colors, and you'll find them used at nice prices. I am a huge Gretsch fan, and currently own three of them including a custom 2220.
Sweetwater has these at $229 new, and they do not disappoint.
