I've spent an embarssing amout of time on this lol.
Pageplus uses Verizon's prepaid 3G Network. I've been looking at getting a used smartphone that is 3G capable.
Two Pageplus retailers that I have been looking at are kittywireless.com and beigephone.com. They resell Pageplus plans at no markup, etc. Maybe check them out and find what you want. They also have a limited selection of BYOD at decent prices. kittywireless has a forum and there's a used cell for sale forum there.
