It all depends what budget you have.
If you have $800-1000 go for the best cookies: epia m10000 (+rest hardware), opus, xenarc/lilliput/anything else with vga,
If less than that: use some spare parts from your computer and build system, probably inverter (or if you have knowledge build your own opus ;d) and lcd (up to you)
But first use search option, there is many like you just starting out so all questions repeat, you'll find something usefull here for sure. good luck
