From what I know, HPT accepts PayPal, and they're a solid vendor. As for ERP, that's the vendor I like best (big ups to Linda!), though I'm not sure they accept anything besides crypto.
Truthfully, whatever advice you get is already sitting in the crypto threads on here. To put it as plainly as possible: grab an Exodus Wallet, buy USDC SOL, then forward it to the vendor. The tricky part is everything in the middle, so you don't end up with the wrong coin or watch your funds vanish into nowhere.
Begin with vendors who take Paypal.
