Umm, have you checked out Netopia? $500 gets you a SDSL R7100 router which does NAT, Firewalling, DHCP, BootP... They also have these things for IDSL(Sucks) and ADSL. Mine has two WAN ports, meaning I could get 3MB for the cost of two lines. DSL doesn't have the uptime a T1 had. Telcos don't dispatch for DSL outages until weekdays, and even then response is REALLY slow. Only thing is that Netopias use this whole Menu based deal which is crap compared to a Cisco. If you're really cool you can get a R7100 CSU DSU to hook up to your Cosco via V.35 adapter and even use DSL as a cheap backup line for your T1.
