Predetor you are correct, if you are going to use it like a good boy chonda will work for you.
I am not aware about united 125's quality thats why I was bitt hesistant to coment on it, but I do know that even 20years old pointer has good quality material used in it and if a good mechinic has reworked its engine believe me it will not disappoint even you do a tour on it.
I have seen many types and quality levels in China Bikes (totally my personal view so please don't take it offensive in any manner )
1 - Like I have seen forums on Super Power Deluxe 125 which has very poor quality as some users have shared there experience on PW here.
2 - Then I have seen very poor remarks for Pak Hero 125 too
3 - Another 125 I saw rarely is ghani 125 and I have personally seen it getting abused by a person who live near my area and I am impressed by its quality.
4 - then comes a Paiggo, which is an italian Brand but being manufactured in china (just like ur nokia, or Iphone) but has really impressed a lot of domestic daily user in Pakistan, due to its good qaulity and hottest looks. but I hate there spare parts cost. damn expensive :(.
