I am going to have to use HSRP for WAN failover with my two routers since a routing protocol is not being offered. In order to make sure my active router doesn't get out of sync with their active router should any router fail, the best thing I have come up with is two put two trunked switches between my router's and the provider's to make sure if one goes out, the active routers don't get out of sync.

Here is a diagram I found that basically illustrates the setup (So I am talking about the switches between the routers):

Anyways, can anyone recommend the cheapest cisco model for this? I will want to be able to to have multiple connections between the switches to reduce the risk of split brain, and will need one with solid STP. Also, I would like it if I can have redundant power from a RPS 2300 for each of them. I would also be open to Power-Connect options that work with the the dell rps-600 redundant power.

Ahhh, OK I see what you're up to - I'm too used to being in the datacenter where the intermediate switches aren't mine :-)

Depending on the speeds you need any switch should work - for relatively cheap Cisco gear 2960 (or 2960G if you want gig) models will work with the RPS2300 and if I remember right they're as STP- and trunk-friendly as anything else Cisco makes, and you can go up in models from there if you want faster forwarding, more features, etc...

Not sure about the Dell PowerConnect stuff, but I imagine the same applies as long as you can do STP and trunks.

I would probably go for something in the Cisco 3560 series of switches (or 2960 series if RPS isn't a priority). Expected speeds and other requirements (i.e. QoS) would help narrow the selection process down a bit.
