Would not have been my choice. Much better would be to built your own mame pc based around an old ATI Radeon HD VIDEO CARD, special CRT Emu driver for lots of 15K lowres resolutions and top it off with Groovymame, by far the best MAME built ever.
Such a complete setup will cost you also about USD 200 (mobo, processor, memory, HDD, videocard) but will give a much better, if not perfect, emulation experience. Arcadecontrols messageboard is the home of the Groovymame development.
