Mark,
I'm UK based too. I got lucky with an EBay purchase of a used business grade laminator. It is the same model as this one..
http://www.ebay.co.uk/itm/Laminator-A3-GBC-Heatseal-H425-High-Speed-Laminator-/281857258687?hash=item41a00074bf:g:KPYAAOSwAKxWVZXh
2nd hand it is 60 quid but look up the new price and prepare to be shocked.
The GBC I have is perfect for the job of toner transfer process. Cheap home devices that I've tried don't get hot enough - perhaps if they have a temperature knob that could be turned to full they would catch fire! - With a quality business model that's probably less likely. Mine is very well made and will probably last for years.
Kind regards
