Dr Reddy - The Private Clinic (only does FUE)
Dr Ball - The Maitland Clinic (Does both FUE and FUT)
1) Take your time and do plenty of research. Do consultations with a number of clinics/surgeons and ideally try and do a couple in person so your loss and donor area can be evaluated properly. Look at cases which are similar to yours.
2) I know in the real world it's not always possible, but to a certain extent, try not to let price have too much of an influence on your decision. If you have to save up to see the surgeon you want to go to then do that rather than going to someone you are not totally sold on but may be cheap.
3) Don't let travel become a factor either....there are great options in North America.
4) Keep expectations realistic, especially if you have advanced balding and understand there's only so much you can do with a hair transplant.
I see you stopped propecia after a year. If you still have a lot of hair and won't be taking propecia going forwards it's not an ideal situation if you go ahead with a hair transplant. You can obviously still go ahead with one but you'll need to be conservative (i.e wouldn't be going around lowering the hairline, using grafts for temple points, throwing too many in the vertex/crown area etc) with one eye on keeping enough grafts in the bank for future loss but a good surgeon will have a game plan for future loss.
If you are in your 20s and still have a lot of native hair and won't be using propecia, I'd probably consider holding off a hair transplant to be honest. If on the other hand you've lost a lot and a clear pattern has developed, then wouldn't be so much of an issue.
