Cisco switch capability

Hello,
I have a quick question regarding Cisco switches.  We will be replacing all of the Cisco switches in our DMZ with models that have 10/100/1000 ports.  Currently we are using Cisco 3750’s which work great but they all have 10/100 ports.  I’d like to get 3750’s with gig ports but our budget won’t permit it.  I’m currently looking at Cisco 2960G’s and Cisco 3560G’s.  All of the traffic that goes in and out of our DMZ contains attachments.  We also have large database servers that perform real-time replication between them.  I like the 2960 switches but I’m not sure if they are designed to have large amounts of data going through them all the time.  I’m certain the 3560’s can handle it but they are almost twice the cost.  We can get two 48-port 2960G’s and two 24-port 2960G’s for the price of two 48-port 3560G’s.  We are not doing anything fancy with the switches (L3, rate-limiting etc) just straight layer 2 switching using a couple of VLAN’s.  I’ve called Cisco a couple of times and they tell me they will have a Sales Engineer call me back.  Nobody calls.

So my question is this - is anyone using 2960’s in a high bandwidth environment?  If so, are the switches working well?  Are there any justifiable reasons to spend extra money on 3560G’s if we are not using them for QoS or anything fancy?  The 3560’s have double the Flash and RAM but other than that I can’t see any differences between the switches.  I need to make sure the switches we purchase are able to scale with our growing business.  I was hoping someone at Cisco could tell me but they won’t call back.

Any comments/opinions would be greatly appreciated.

Primary difference between 2960 and 3560 = Layer 3 and PoE
These switches are built as workgroup switches, not high-traffic, high availability data center switches.
Depending on how you aggregate or connect the switches to the rest of the network will determine what is best for you.
Cisco's recommended DataCenter/server switch is the 4948
http://www.cisco.com/en/US/products/ps6026/index.html

This switch has the highest ratings as being one of the fastest switches on the planet.

Are you still working on this? Can you close out this question before the cleanup crew gets around to it?
Thanks!
