It makes sense to try them out, regardless of price. Either way, go to high end bespoke places and get an idea what to look/ask for. I am sure some are honest enough that you could say "hey, I am going to asia for a trip and plan on getting a made to measure suit, as I can't afford one here, can you give me some tips of what to look and ask for?".
