My concerns would be three:
- They are relatively new, little over a year old (Nov., 2011)
- They are hosted on Softlayer, not necessarily bad, but as a reseller you would want to know they were offering extra value for the extra cost.
- They are significantly more expensive that many others.
My general advice is to either go with an extra value reseller you know something about and can trust (as with Lisa's Website Palace) or stay with one of the absolutely trusted players.
A majority of the top members of this forum use and recommend Hostgator. I and a number of others that I trust here as being knowledgeable use Dreamhost (I have happily used them for at least six or seven years and they have over one million sites hosted). A good number also recomment Bluehost although I have no personal experience.
A lot of folks recommend small hosts and often ones no one has heard of before but I would be very careful who I listened to on this topic since there is a lot of uninformed advice.
