I’ve ordered from Studiospares a few times, they’re a pretty good company and reasonably priced. I can’t vouch for their own-brand stuff e.g. cable/connectors as I tend to stick with Van-Damme/Neutrik, but as a company they’re pretty well-regarded. They once only sent me half of an order by accident, but when I called them about it I managed to speak to the bloke who’d actually picked the order, and the manager (I think you’re right about it being a small company) and it got sorted fairly quickly when they could have been awkward about it.
