I really like Bigsby's too.
I didn't want to pay the higher price
for a guitar that already had one mounted.
There was no way
I was going to drill holes
in my R8 Flametop
so I bought an inexpensive Wine Red Studio Les Paul with gold hardware and bought and mounted the Bigsby myself.
I have just a little over $1,000 in the below Guitar.
I also mounted a Bigsby on my modified "Lucille" (shown below too).
