I did for most of last year - ds1 was 7.
We loved it but ds1 did miss the social side of school (its only plus IMO) and he has been at his new (much smaller) school for a year now.
I would HE again in a heartbeat though if needed!
One of our issues was that we live in a very small village and there isnt much of a HE community - this is not the issue if you live in a bigger town/city. Large cities usually have a very busy HE community.
Have you googled Education Otherwise? You can join and get the details of groups near you.
Also, check out the HE boards on MN...found them VERY helpful.
