The gear listed in my system (sans cables, tubes, power conditioning, surge protection, the rack and custom shelves) was purchased for around $1300.
Love this system and have been using it for 20 years now.
The mini system I use @ the computer (Sharp SD-EX111/Polk RT15i) was purchased for $88.50.
$75 for the Sharp on closeout (had been $500) and $13.50 for the speakers @ a local thrift ($15 less my senior discount;-).
I owned/drove a Citroen DS-19 for 8-9 years and the cost of doing so (including the purchase price, annual insurance/registration fees and maintenance) came in @ around $10K.
When I compare that car to an equipment rack or a cable selling for around the same price ($10K) things become both more confused and more clear @ the same time.
I find it difficult to judge anything by its cost as we all have our different takes on "value".
The following link shows a DIY system that definitely cost more the the $88.50 I spent on the mini-system.
