Yes they are goodÂ

~ though we compete because I founded "
http://aimtechng.com"
I know the founder of W4Africa in person and the company is reputable. So, I assume they should have quality service.
Give them a try; if they fail then @
http://aimtechng.com is there to rescue you; we have free migration service even if you have uploaded your site them. But from a clean mind I'm sure you'd find them OK!
All the best, enjoy hosting.
