This topic is discussed many times.
- Wacom is the best, true. But for your budget you can get small tablet with only 1024 lv of pressure + other spec is in amateur league. This is good for chikd, also photographers use such products, they do not need something better.
Size is important just like level of pressure, this is discussed also. I personally use old Genius 9"x12", even this tablet have many fails is better than this small Bambo, I check my self
This is probably mu next tablet.... do not have enough for Wacom Intious pro L
Do not forget, tablet is not things you buy every day, so chose wisely .
