Strings can make a massive difference. I use Tomastik Infeld on my semi Acoustic/electric hybrids..
Not the cheapest string but they do last at least three times longer than ordinary phos bronze strings.
My last build has a set of Tomastik George Benson Jazzies, but at $60 a set that might cause heart palpations...
I do like the Thomastik Enfield, they are some nice playing strings, but as you say they are a tad bit pricey and often difficult to get a hold of. I've often re-strung my Casino with them.
FrankenLab Hand crafting guitars, because Death Rays are expensive.
