I wouldn't invest into twinking a melee in hopes of someday recouping the money or making more than you put into it.
That being said you're gonna have the most fun out of twinking a melee class, you only really feel the investment if you're whacking something or getting whacked, putting that money towards a nice monk stick would probably yield the most bang for your buck?

and then random assortment of smaller bits and pieces, HP rings, azure sleeves and targishin bone mask, the rest for a tink bag?
Also depends on what server, will be much cheaper on blue! Those are green prices/suggestions!
