I also have a PayPal debit card, and I love it. I have a business account, which doesn't cost anything, and earn 1% cash back on all purchases! Love it.
I think (and could be wrong) that if you're selling on Etsy you *should* consider upgrading to a business account. I'm pretty sure with just the personal account, people can only pay you with their PayPal balance, not with a cc. I remember reading that somewhere, I'll see if I can find the info for you :)
