Cost to replace BK ST140 in todays $$$'s & quality

I used to own a ST140 years ago, and now yearn
for it again. I know they are available used, but finding one in mint condition is difficult. I would like to replace the 100 watt version that retailed for $550 back in 1990, and was wondering what that level of performance would cost today and what a suitable alternative would be, thanks.
Try to find another one and send it to John Hillig like I did my M-200 monos, you'll be glad.
Rx8man, I own a B&K ST-140. No dealer network in Canada any longer, unfortunately. Who is John Hillig, and how does he fit into the amp picture?

He is in St. Charles Missouri...he does a hell of a job on most everything...
