I got a Firefly Thin line cost me $151 total. It is a pretty good guitar no problems needed very little set up, lower action, change pickup height, adjust intonation, your basic stuff. no fret sprout or tuner issues good pots. It has to be the least expensive thin line on the market I know of.
Right now I have some Erine Ball extra lights 10 wound nickel and the sound just isn't there yet so I will try some steel 10 next. and I think I will polish the frets and oil the board. I get good balance on the pickups now that I has set there height.
