I'll echo Mike's comments. When I bought my MX6, the LX and MX units were side by each on the dealers lot. Big difference in beef. IMO I do think the LX's are a little pricey for what they are - OTOH I think the MX is price competitive with other brand units of equal beef and features. Make sure you compare apples to apples when you're checking pricing (slip clutch vs. shear pins, chains, laminated wheel(s) etc.,). Your 1070 should handle an MX5 or even an MX6 just fine, though you might need a little front end weight if you don't have a loader mounted.
