As others have said a 34 middle ring will often be over-ridden when trying to shift to it from the inner ring.
What kind of riding are you doing/planning to do?
My touring MTBs have 24-36-48 or 26-38-48 chainrings. They are old school cranksets similar to the Sugino one linked to upthread.
You might consider loting on Craigslist, Kijiji and any other for sale sites for a used MTB from which you can take the triple crankset and bottom bracket. I say that becuase a while back ( a number of years ago) I came across a fellow living out in the country who fixed and sold bikes and charged $40.00 each for them. Over the years I bought a number of MTBs from him that old-school Shimano Deore components, or at least crankset and derailleurs on them. I got them to keep as spare parts.
Approximately where are you located?
Cheers
