If you need access to sites that block Tor I suggest that you just buy a cheap private vps as anonymously as possible and use it as a private exit node when you need to hide that you are using Tor, Tor used to have an option for torrc that let you chain a proxy to the end of your circuit for some sites its been a while since I looked into it though I don't trust VPN services anymore than I can throw them, but of all the ones named here cryptohippie is at least run by agorists I would seriously consider using Tor to connect to a VPS that you own yourself though
