I recently replaced my SCUBA regulators with a new set. Technology moves on apace, and servicing old gear such as that is quite expensive, [especially here in SG! [

I did some digging around, and probably via a px-comparison site came upon a company called DiveInn. If I open their www their contact information gives a phone code in Spain, but their sporting goods range is hugely extensive and well priced, and the look/feel is much more 'global' than southern European, for example you can browse the site in 17 languages...
They split down the sports and products ranges into 11 'sub-shops', for example:
Swimming
Nautical and fishing
Trekking
Skiing
Football
Mortorbiking clothing
Diving
Racket sports
etc...
[Just realised - no golf department!?]
Anywayz, I got some very good quality SCUBA regs from there, and IIRC even with freight and import duty they were still something like 30-40% cheaper than here. Certainly a place I'll be x-referencing again on prices for any future sporting $+ purchase.
The www is http://www.trekkinn.com/outdoor-mountain" onclick="window.open(this.href);return false; . That should take you to their trek shop, and you should see the 10 other 'shop' tabs across the top of the page.
[I've zero connection with them, barring the above order, which left me most impressed].
