Guess I should chime in here.
-- The PowerRouter 2282 has been tested with 100 meg circuit and 15,000 PPPoE users..
-- The PowerRouter 732 is NOT a 820 ONLY, we have had a number of people call in with 820s that have crashed. Just cause it may boot up on a 820, does not mean it will RUN on a 820. The PowerRouter 732 has over 4+ years of product development, testing and production sales. It is more hardware than the 820, it is more settings specific configurations, bios settings, versions etc.
-- The 2242 can handle 4500 users, depending on what you are doing. User counts are not really a good number, however the example I will use is that we have customers running the PowerRouter 732 with 4 GigE internet connections averaging around 900 to 1.5 gig of traffic, full BGP tables with well over 8000 IPs behind it. So maybe your configuration on your hardware can't handle that, maybe you have IRQ issues and thats why it uses so much of your i7 CPU.
How about this, simply put, if you want to go cheap, buy a server, and stick software on it. It may work out great for you, if it does, awesome. However, if you want to unbox a product, plug it in, and configure it, just like you would with Cisco, Juniper, plus not have to worry about it if it dies 3 months from now, guess what, but something with the PROVEN track record.
