In reply to Mike.

For what it's worth, I was a former Websynthesis customer and moved to WPEngine about a year ago.

I regret nothing. The cost was higher, but the service, support, stability and tools more than made up for it. The staging/development/production capabilities reduced the dev cycle issues (for me) significantly.

I don't know the stats on your sites, but you may want to compare whether separating them out into their own accounts would reduce your bill.

If you don't need a 'managed' platform, there certainly are other, much less expensive, options.
