I got a nice pure although I don't have a LR account.. and I think its worth more than 6$ in paypal :3 So maybe you could buy some rsgp and you could buy it with that. http://runegear.net/Thread-Selling-Low-Level-Pure
for $6 paypal i could sell you a lower level (like level 50 attack / str and 45 defence) account. The +'s about the account is that it has a yo-yo and rubber chicken. It's not really much, but you can't really expect to get much with just $6 Paypal.
All my other sales are worth more than $6 :/ if your interested in the one i mentioned just post about it, it's somewhere in the sellers section
