So i have a Laguna LE122. I'm thinking of buying the LE422. Then I realized that i could just add new parts. The reason i wanted a new guitar is for better tuners, pickups, and a locking tremolo. That guitar is $270.

I could totaly give my guitar a makeover instead.

Tremolo: http://www.guitarpartsonline.com/product_info.php?cPath=33&products_id=191 $60
Tuners: http://www.guitarpartsonline.com/product_info.php?cPath=25&products_id=648 $35
Pickups: http://www.guitarpartsonline.com/product_info.php?cPath=27_66&products_id=184 $30
Knobs: http://www.guitarpartsonline.com/product_info.php?cPath=29&products_id=142 $7
Total: $135ish
P.S. i know these parts are cheap, im a 13 year old on a budget
I have no opinion on the question, but you're not going to get a floyd rose in that guitar without routing.
^and $35 by not replacing the tuners. Unless the ones on your guitar are absolutely horrible, they won't make much of a difference. Even then, locking tuners seem unnecessary when you've got a locking nut. There's a technique to stringing the guitar (in one of the stickies somewhere) that essentially locks the string - and it's free.
