Very cheap; suspiciously so.
I wouldn't go so far as to say that.
Cheap? Maybe.
Very/Suspiciously cheap? No.
OK, so £150ph is pretty standard for a TS. There are still quite a few in the £130-140 bracket, but £150 is definitely the benchmark and normally gets you a well transitioned TS.
If you look around, there are even some as low as £100 still. But (and it is a big but) once you get down to that price, you're often looking at someone closer to a cross dresser than a full-on TS. Breasts and wigs make a big difference there IMO.
Judging by the pics on this profile, this one doesn't have breasts so is potentially closer to cross dresser or transvestite territory. On the other hand the hair looks genuine and the eyebrows appear well maintained, pushing us back towards transitioning TS territory. Certainly at least a Ladyboy, although now I'm getting into a whole philosophical debate with myself about where the different shades of grey meet.
Purely judging by the pics available on the main profile (because no PG is worth £24!!), I'm guessing this one is priced appropriately for her niche within the market.
I mean don't take any of that as gospel, this is just my take on what's there to be seen and I've been wrong before. But I've also been pleasantly surprised when expectations were low.
