It looks like my last post wasn't clear enough, so here once again in bold large letters:
I have come to a decision, and have pre-paid new arrangements already!
Specially sorry for Luke that he missed out - his offer was rather decent
Webair hasn't even replied to an email enquiry - looks like their entire office was closed for Easter!
I decided to stay with my TGPs at phatservers, mostly thanks to Mike Wesson, their excellent tech.
And I guess Sly wasn't persuasive enough to keep me for my galleries, hence I signed up with a different company for cheaper bandwidth-heavy traffic.
Once again thanks to everybody who replied!
