I have 4 onkyo products, a tx-sr605, tx-nr807, tx-nr3007, pr-sc5507
Onkyo offers great bang for the buck usually.
With onkyo, the QC is hit or miss at times, i have not had any issues yet, but there are a lot of people with issues. Keep that in mind, onkyo is not known for great qc.
another thing to consider is that onkyos usually produce a good deal of heat and should not be in tight spaces.
