Hi Jodi,
No doubt with <= 2Gbps of vanilla HTTP/S you could roll your own with linux, a modern Intel with AES-NI and script glue.
What you get with appliances (F5 in particular, but other vendors as well) is the ability to do crazy wonderful in a predictable and simple way. An iRule to remove a null value ( : ) HTTP header created by a brain-dead browser from the dumbphone days; or timestamping the first request, first response, final packet and final browser load-time (network, server or client problem); spring to mind.
With that in mind, I suggest you look at load balancers with the corner case problems you want to solve, and the vendor's solutions to them.
Thanks,
Jed.

Many thanks to all who've replied
To be honest I hadn't considered SSL until now as many of our sites are still vanilla http - however with the way things are moving we should probably plan for it
To narrow things down at this stage we're currently sitting at ~50-100meg traffic with ~2000 active sessions. However we want to plan ahead and install a decent infrastructure now, which can be easily scaled up when/if required

Hi Jodi,If it���s web traffic, safe to confirm SSL too?��If so; and it���s decent volumes, ignore the base model F5s and A10s - the next step up have hardware-based SSL offload, which increases capacity markedly.�� We needed the A10 3030s, as running campaign sites means we can get 10,000 visitors wanting to establish SSL sessions in a very short space of time, and moving ~10Gbit/s of traffic.��As others have pointed out - a more robust use case scenario would help narrow down the choices.��Cheers,KarlOn 11/11/2014, at 11:16 am, Bill Walker <bill@wjw.co.nz> wrote:+1 for F5's we use them here

Hi Jodi,
The old Alteons are excellent :)
We run F5 virtuals here (they cluster well) and a combination of
virtuals + physical F5 units in AU.
Have been testing KEMP Technologies as well - they have an excellent
Aussie team based in SG.
Cheers
Darren.

Just been pointed out that I forgot to add what we're aiming to load
balance
at this stage it'll be mostly web traffic, but also looking at
possibly pop/imap/smtp and streaming on port 1935 later on down the
track
cheers

Hi All
Just wondering what people are using these days for dedicated load
balance appliances. Last ones I had anything to do with were the
Alteon Ace Directors going back 7-8 yrs so am a little out of touch
with whats in use today.
Cheers
Jodi
