domain ComputerandNet.com - Appraisal please

[Karthik2k9]

I had recently bought 2 domain names for my PR 3 blog,with the intention of using one and selling off the other...

I am new in this domain name selling field,and I would be happy if you could tell me the worth of these two domain names

1) www.ComputerandNet.com -Two highly searched keywords-Computer and Internet.

2) www.BestServicesOnNet.com

How much does these two worth? Which one do you like?

Thanks in advance
