I also have hosting with I-Web Solutions & am amazed at what you get for the price - both the package & the customer service feel like they should be much more expensive.
I also have purchased a domain from 123-Reg, with no problems, transfer of the domain to my hosts DNS was hassle free. As I bought a 'co.uk' I just got my nominet confirmation sorted
One of Cable Forum's members sells domain name registration, it may be worth having a look for comparison - check out the link in the sig of Mr_love_monkey.
