Long-time modeler (since childhood and I'm now close to 50) who has been inactive for awhile due to space and financial limitations. Now starting up again, mainly with collecting locomotives, rolling stock, and structures for right now. Have a moderate amount of N Scale stuff but considering going to HO Scale due to peripheral neuropathy in my hands making fine detailed work difficult. What is the cost differential between the two scales?

UPDATE: I've finally decided and I'm making the switch to HO.
