How very timely - I came to the shop after a long time away, seeking latex, and find this thread in the forum just as I was about to give some feedback!
Anyway, to answer your questions:
1) Haven't tried Datex but I like the feel/fit of latex against skin, so it doesn't overly appeal (by all means send me a freebie to review & change my mind! ). Chlorinating the latex makes it easy-on/off, some suppliers now offer this as a service, hint, hint...
2) Coloured latex yes but mostly my purchases are for the feeling rather than style so plain old black will usually do.
3) Tricky, I'd say it's about even - Datex sounds like a more convenient gateway drug for newcomers, if that makes sense... possibly many would pay a bit more for the convenience? But I'd pay more for real chlorinated rubber any day.
4) If I was in the market I'd expect to pay £200+ for something decent (nicely made in the UK) or £100-ish for some cheap chinese thing. Currently I would not be shopping at LH for expensive rubberwear though, sorry guys.
5) See #3, very hard to guess, probably same answer as latex TBH.
6) Specialist, then lovehoney on the offchance I can combine a few other non-latex bits in one naughty order... hasn't worked so far as you guys have a limited stock...
I came here today as you guys are listed on Denber Rubber's site as a stockist, but you haven't got what I was after (#126D bermuda shorts). I was actually initially after Latexa's version as they're better quality but Denber are UK made and (usually) cheaper.
It's a shame as the UK has quite a few home grown manufacturers (Sealwear, Denber, Kastley, Cornwall Rainwear, Westward Bound...) that range from high fashion to utter filthy depravity (in the best way!) and you guys sell somewhat naff Sharon Sloane stuff which is bound to dissapoint.
Also, you seem to shy away from any of the more kinky stuff which I find odd, I can't beleive there's not a bit of market out there for it, possibly some of your customers may not even be aware this stuff exists for general purchase & where to get it.
