The HP 2530 looks a good alternative, with a switching capacity of 104Gbps but it does lack 10Gbps options (as above). In theory though you could team multiple SFP ports which is a cheaper way of doing it.
HP 10gig fibre modules are still quite expensive as well!
Switching throughput is usually based on port count, so the Netgear 724T at 48Gb is exactly the same as the 2530 at 104Gb. One is 24x2 for full duplex, the other is 52x2 (48+4SFP).
Throughput numbers do need to be considered more carefully for *modular* chassis switches and those with stacking, SFP+ and other 10Gb interfaces.
The 2530 and newer procurve switches (been using the 3800s recently) are much better with fan control now, certainly not like the old 2800s and 2900s.
Millgate). They're great, not had a problem with them, powering VOIP phones and wireless access points. I wouldn't have said they were that noisy.

Any reason why the upgrade from the netgear ? I run those switches without any issues with vlans and they are pretty solid - admittedly they are cheap but they do the job. I run toughswitches for PoE for unifi.
I admit the interface is pretty cumbersome and has changed over revisions (the older switches I need to use an old version of firefox to stop the interface from crashing) The newer ones seem fine. I only run one VLAN for wifi guest access but it works well enough - whether or not I've done it correctly is another story! Of course with these switches being only L2 I can't bridge the VLANS and I need to do that on the smoothwall.
Upgrading switches because you can't understand how to VLAN them seems an odd choice. The Netgear switches you are talking about shoudl be perfectly adequate for your edge switches.
From expereince they are almost identical to HPs to VLAN (if using the GUI), you create a VLAN, then Tag, Untag or neither the ports on the switch. Pretty simply really.
Just going back to the noise of the 2530s. Just powered 2 2530-24Gs up from under the desk. As it stands at the moment they are silent. Can not hear them at all. I literally put my ear to them, cannot hear them.
If you need any help specing this up etc, let me know and I'll get one of my guys to give you a call
I had exactly your problem a couple of years ago. I searched the internet and struggled to find a simple article explaining the basics of VLANs. I learnt a lot from forums on Edugeek and sought help from colleagues in other schools. Setting up VLANs on HP switches is easy if you know what you are doing! Like anything, it is hard if you don't understand it.
I use GBICS, mix of SMC and Netgear ones, some switches can be fussy with makes - not sure which are compatible with these switches so to play it safe I've stuck to netgear from now.

I'm just installing a mix of 2920-24 POE and 2920-48 all linked by stacking modules and then 10Gb SPP Modules back to our core.
so far I'm very happy with them.
