that tablet megaton has is actually a generic tablet, i have one too only mine is made by Trust around £60 - £90 in the UK nowadays. its dire, it needs a baterry in the pen, and he's obviously not showing you the mouse as it's absolute rubbish and also needs a battery, the sensitivity curve is not in the same league as wacom tablets. and many of those tablets have rodents with no scroll wheel (which is useless) and the pen has no eraser, the wacom does. my only gripe with the wacom tablet is the scroll wheel isnt teribly robust and you could be replacing the rodent after about a year, the wacom pens are of the highest quality with each pen having a unique ID code, this means that if you have several pens, you can assign different tools to each of the pens via the tooltips software. ( i use a grapphire tablet not the trust one, i should sel it on.)
the only other make of tablet I would consider is a cherry, their 'digitizers' are awesome and their tablets are just as good. wacom tablets also come with corel / metacreations / procreate painter. worth more than the price of the tablet alone.
smart artists would go for wacom.
