(usr-tc) TC Hubs??

We're using TC chassis presently as our local telco is still 33.6 POTS connections. We're looking at buying other RASs and going PRI when the telco turns up their 56k/ISDN service next week. I'm not that familiar with any other RAS products out there and would appreciate some feedback on what to look for as far as price, reliability, support and leasing. Are there any decent discussion groups to join to get better informed or can you enlighten me here? Thanks in advance! Dave Ashworth Jam21.Net Fort Frances, ON
