Was considering this issue the other day.
For a deal this small the letter of credit route is impractical - and it's a bit disconcerting when they don't take PayPal or a credit card (which would give you comeback).
My view was the risk that goods would not be up to scratch - often the case with electronic goods from ROC apparently rather than not turning up at all. (I was looking at hub motors). In short, unless you're dealing with a uk or eu entity, theres no way you'll get your £ back if the deal goes sour.
The only solution, TMM, would be to buy a very small quantity as a sample and only reorder if the deal works out on both delivery and quality of the sample.
Im looking for a European source for my motors...
