welcome to HTN Bugs
as "thanatopsis" said,Location should be your least consideration if you are looking to get a decent HT.I went to Canada for mine !
Also,though hairline requires a more artistic surgeon,the nature of the HT is still the same regardless where you need hair:
Hair removal from back to the where it is needed
So don't think that since you don't need a hairline job,anybody can give you a good HT !
finally, my logic is this: if you are willing to pay lets say 6-8 K to get it done,then a 300 to 400$ for a ticket and hotel shouldn't be a big factor for you on you decision.
