Sir Jerix, saan location mo? You can pm markcrenz, taga Proj. 8 QC siya. If he has time, he may be able to help. One thing for sure, hindi ka niya sisingilin ng mataas tulad ng Love E. I can relate with you, am really not comfortable tinkering, so next best thing would be a trustworthy and reasonably-priced repair guy.
Hehehe sir Tony may be correct, don't believe all the posts and praises you read here. Ang daming magaling chuwariwap ekek dyan, praising their friends' gears blindly.
Btw, I also think your seller may have acted in good faith. Baka medyo minamalas ka lang, and bottom line talaga, caveat emptor. Good luck bro!
