I had gifted a Mitashi Game in Champ to one of my friends child, it lasted for 2 years when its cartridge to place game cassettes was not working.
I have got to tell you that it had fell down many times after which it stopped working, but its totally worth its price of Rs 800. I had bought it for just rs 800 from Manish Market in Mumbai and it came along with 1 free 8 bit gaming cassette with 64 games inbuilt. It also had 2 joysticks, its actually for kids but its got a few games like mario and road fighter which even you can enjoy and will remind you of your childhood.
The best part is its joysticks were cordless and it is very esay to connect to TV and it comes with wires to be attached, but the only drawback its spare parts are hard to find in market, so if anything goes wrong you have to throw it away, but its fair looking at its price tag.
