I use the CyberGuard SG530 for my personal VPN needs. It's a box about the size of your average 8-port switch, it runs a version of embedded linux and come default with PoPToP for PPTP v2 and FreeSwan for IPSEC. It has a web based config and if fairly painless to set up.
I was searching specifically for a PPTP device simply because it is so easy to configure and use, especially for Windows-based clients.
If you have a spare computer you wanted to use for this, you may want to look at IPCop, but at about US$350 the sg530 is not a bad alternative.
