That is about the same, when a new model comes out, nobody wants the old model, so its worth nothing anymore compared to new price.
I have these pioneer CDJ cd players, i bought them just before they released a USB cd player, that aint going to happen to me this time with my scope money.
I am looking for buying the R&S Hameg HMO 1002.
Ofcourse if it is a good product, it wont need replacing, good brands dont replace often.
On the other hand, technology goes very fast, and releasing new stuff sells more.
I would buy the HMO 1002 right now if i had the money, since i dont think they will discontinue this one very fast because it is a good brand.
So its very double, i can spend my money only once, meanwhile i still use my old phillips scope, only its drifting with high frequencys, and getting vague.
