wow $190 that are not even £ 120 , for that money you maybe just get a imac g4 700mhz 15 inch model here
like that one sold for exact the 190 dollars if you convert it , and can be considered as a absolute bargain
for a 1.25 g4 iMac with 17" you look at about double that if its in good condition even more
for the 20" you can easy triple the price
so if you ask me $190 are a bargain if its in working condition 🙂
