The best way to have a Martin you love is to buy an old 00-18 used for $225 in 1972 and play it every day for 33 years except when it's in the shop because you maintain it carefully. You can get an old Gibson LG-1 for $300 off of Ebay 4 years ago to play for variety and to remind you how great your Martin is.

Good instruments are a matter of quality, price, maintenance, personal taste, and the good sense to love what you have rather than suffer because there may be a better instrument out there somewhere.
