I have bought 3 'Chibsons' (Les Paul Standard, Les Paul Custom and ES335) plus a Strat and a Ricky bass from Chinese suppliers. You need to regard them as project guitars, because although the construction and finish are usually first rate, the hardware can leave a little to be desired. On my Standard for example, the only original parts left when I've finished with it will be the tuners, pickup selector switch, stopbar and 3 of the 4 pots. Everything else will be changed. Some fare much better; my Custom is having a new pair of pickups, and the tuners are only being changed because I prefer the shape of the new ones. All other changes are cosmetic - knobs, truss rod cover, pickguard, etc.
Taking the Standard as an example again, It cost me £220 including carriage from China, a hard case and import VAT. Total spend after changing all the parts will be £318 (although selling some of the original parts could reduce that). Compare that with a real Les Paul and it represents a massive saving, and I'm convinced that it will look, play and sound almost as well as a real one, especially after a bit of a setup. (Admittedly I can do fret levelling and profiling, and replacing and shaping the nut myself so don't need to pay someone else for these).
Now I don't need to tell you how expensive Gibsons are, not to mention Gretsch, Rickenbacker, PRS etc. For a Fender, buying from China doesn't represent so much of a saving. In fact (even though I've done it) I would not recommend this approach; a Squier, a Mexican Standard, or a (secondhand) Classic 50s/60s/70s Strat or Tele would make a much better starting point.
With regards to Burns, I've not seen many on offer so can't comment; websites you can try include TradeTang, D H Gate and the one I used, AliExpress. For further information, look at the China Guitar Sceptic videos on YouTube, or his website:
http://cgs.x10.mx/index.htmlThis includes the Chinese Guitar Forum, where such things are discussed and new purchases reviewed by the buyers. Finally, don't forget these things are FAKES, FORGERIES, COUNTERFEIT, call them what you will. It's not illegal to buy or own them, but some of you may have ethical objections. (It is however possible to order one of these guitars with any name you like on the headstock so if you are unhappy about ripping anyone off ... you don't have to.)
