Since I do this for a living I'll tell you the main things my company needs to look at (and we are technology agnostic... we want the best cheapest solution).
Do all phone services for the building come into a single POE - Point of Entry, often called the M-POE?
Is there riser cable from floor to floor? Is each condo home-runned? Do you have RJ12 (3 pair) cable or 4 pair cable (cat 3, 5 etc)?
What's the distance from your wiring point to the furthest unit? Use a TDR test set.
DSL ~15,000 feet.
HPNA+ ~4000 feet.
Ethernet ~300 feet.
If you have 1 pair (free or not) and it is not a digital line you are pretty much stuck with DSL or HPNA+. DSL will be the most expensive (new). Check ebay for DSLAMs and modems.
If you have 1 used pair and 1 free pair and the used pair is NOT a digital line you can use Ethernetsplit.
If you have 2 free pairs you can use Ethernet tho you may see some interesting cross-talk. Even if you are bringing in a couple of DS-1's (MLPPP, IMA) use a managed 10bt Switch. For example the Nortel 310-24t ~$40.00/each.
CPE
Ethernet 10-50
HPNA+ 40-60
DSL 50-200
Installation Labor = $$$
Ethernet will require the most effort as you will have to terminate the in condo daisy chain (if that's how they did it which is likely) at the point you want to wire in the RJ45.
HPNA+, DSL will be the quickest.
Space and Power
you'lled about 8U of rack space for that many units regardless of the solution. you *might* be able to wall mount if you distributed wiring points. Make sure you have good airflow in the locations you choose and limited or controlled access.
Public or Private Addressing.
You will have the least problems if you can do public addressing and then rely on the users to implement their own firewalls etc. Realize any computer directly connected to your network will in most cases be able to see any of the other computers directly connected (ie. not behind a firewall, or if you don't set up VLANS or use partitioning in your DSLAM. For 151 units you'll need a/24 or a/25 and a/26 with two different networks (multiple ethernet ports on your router).
Management
Make sure you set up ACL's for IP's that can manage your router or switches. SNMP and VLAN is good 'cause you can easily shut off service remotely for non-payment.
