yh they say a nice number to start it off is 500 but think you can get it a little lower.. yh it is as much as you want when you want.. my aim is just 250-300.. seeing a surgeon on 5th april then a diff one on 22nd then see what they say with booking a date.. im not in a rush to book a date as might have it sooner or later than the date they give so probably wait a little x
