Not easy to answer because Lima MM 201s were replaced by the superior Murphy Model manufactured 201s which have infinitely better motor drive chassis. MM 201s are selling new through retail channels from €135 to €179 depending on livery.
Lima made 201s are rare and only available on eBay, used to sell at astronomically daft prices before Murphy Models launched their far superior 201 which caused the second hand value of Lima 201s to collapse. There are still the odd few 'head in the sand' types occasionally trying to sell them for upwards of €350, but they aren't selling at those daft prices anymore except to the odd unfortunate gullible punter.
IMHO a new Lima 201 is not worth more than half the price of a new MM 201. The MM has centre drive chassis, both bogies powered, four axel drive and all wheel pickup, hence its low speed performance especially over point work puts the poor Lima chassis in the shade. Add to that 201 prototypes seem not as popular as 071/111, 141/181 GM model locos.
