Also there are SIP-to-Analog adapters: for example, Cisco SPA2102 costs around $60, and it supports 2 analog phones.

I'm a fan of the spa-2102. It won't let you do any fancy SIP stuff... no presence, no built in transfer or the like, no big caller ID screen. But they seem to be pretty reliable. It even seems to handle NAT pretty well. Provisioning is pretty easy and fast.

Just my experience. It's an ATA not a sip phone, though...
