I have had most good experiences with this company; they have a large selection of parts for older out of production models.
Shipping alwasy has been quick and welll packed
Price are at the lower end for the uk and especialy compaired to local irish shops
Sometimes they fail to reply to email info request so its quicker to just call them,
Website looks well organized but at times they fail to remove discontinued items but this is only sometimes for the really old parts.
An aditional service is that they have parts diagrams of several older helies on there site so you can check the parts you need.
The one issue i had with them was a pair of main blades that had a defect; the box they came in was still sealed so they had not inspected them bevore shipping.
I first provided pictures of the defect and send them back and got them replaced.
In all i can recommend this store.
