EntroPay/PayPal/ebay Help/Question

So I have 2 of my paypal's limited..with $800 in. Pretty anonnyed but also with those accounts are my credit cards. I want to buy something on ebay but was thinking to get an entropay account then pay using the entropay card without regestering to paypal through the checkout..would this work? And if i had any problems how would a chargeback work? i'm uk based so if u guys know any other way i cud use the ccs attached to the limited pp's please help me by explaining how..

anyone who can help be dearly appreciated
