Shower cubicles

I need some feed back please. I am doing a bathroom reno and I am looking at s shower unit. I have seen many on E-bay and also at reece plumbing etc that are units all-in-one.
What do people think of the all-in-one units like the ones on E-bay??
Also what do people recommend as a all-in-one unit?

Many thanks in advance for any advice

I would prefer to go to my local, well respected supplier for something like a shower unit. Get advice on all the different types and go from there.

You never know on ebay.
