What is your comfort level?

Can't say how or why, but while perusing the Classifieds I've unconsciously set limits on how much components, new or used, can reasonably cost in my home system. The limits seem built-in. Although units over my limits are often desireable, because they're beyond what I'd consider actually spending, I give them no more than passing interest. Have I found my comfort level? Thankfully the used market on the Net has got me into some stuff I'd never have afforded new. FWIW then, here are my limits:

Preamp - $1,000
Power Amp - $1,250
CD Player - $1,500
Speakers - $2,000
Pair of Interconnects - $100
Digital cable - $150

Do you have limits? What is your comfort level?
