Yeah, I've got one. It doesn't get much action right now as it can't hold a candle to my Carvin but I'm thinking of modding it at some point...here's a review I did:
LAG Arkane A200ST Shred Reviews
The best improvements out of the box are very easy - new strings, set-up and new wiring/pots. That's probably around £50-£75 at which point it plays and sounds as good as it looks. The stock strings are dreadful and the pots + wiring aren't the greatest, but the stock set-up is suprisingly good..or rather, it was on mine.
