Right now I own a Sherwood RD-7103 reciever that cost $120.
basically this one:

I own a Jensen 5.1 Channel Speaker set that cost $100.

Then I decided to upgrade (may have downgraded) the two front speakers oh my Jensen set to KLH L853b 3-way speakers for $20.

I got all that stuff on sale at Circuit City. I am not sure it is very good equipment.

I was thinking of upgrading my front two speakers, again. I will spend about $150. What should I look into?

Also, can someone tell me how bad my stereo is. Is my reciever any good? Be blunt.
