I didn't choose the Xraid, having only used a mac mini up to that point. It is very pretty, and speed is decent.
It is, as you say, not well designed. The fibre card is a custom apple version, with copper (for FC?) connectors! No controller redundancy is bad, and the first time I had a disk failure it had an error, didn't mark it as dead and took the whole volume offline instead.
I did look at the Equallogics but I just can't afford one right now, and they have loads of feature, but most of which I don't need.
The MSA1500/1000s are a bit limited, but the 2000s seem to be ok.. It's dual controller with 12 15k 300GB SAS drives with 3 years HP support for just under £7800.
The closest one (for actual space/drives) for Equallogic was around 21000 for 4 less drives. The features and extra NICs just weren't worth the cost for a secondary SAN. ESX support from 3.5 onwards too

(In fact I was picking SANs from the VMware compatability list).
