Looking to pick up my 1st Vinyl cutter. Im brand new to vinyl but not to graphics/design

Im a Graphic Design student and i thought it would be a good idea to sell stickers/signs/car graphics/business lettering and logos on ebay to make some extra money.

What would be the best Vinyl cutter for under 2,500.00?
I found 2 that looked decent from a good e-bay seller.

Are those 2 good or should i look at another in the 2,500.00 range?

Do cutters/plotters in that range only cut 1 color graphics?

Can plotters/cutters do anything other than cut graphics?

How long do they typically last before needing new parts?

Thanks!
