Aldi are selling a 216-S Janome sewing machine this week. This is a pretty good entry level machine. They have rebadged it as the "Stirling" which must be an Aldi branding initiative as they also gave the same name to the last Janome machine that Aldi sold which was the DC2050. The 2050 was a better machine than this though.
Normally sewing shops sell this machine for $180 or so, so $100 is not too shabby.
Please be more specific than $180ish, we need a real estimate
