I've recently got this. So far I have used the Auction sniper, Kitchen Quest, Rubbish Dump Grabber and Shape Shifter Solver.
I had no problems whatsoever with the last 2, they are great.
The problem I found with the Auction Sniper is the database. The prices are really out of wack, I bought a few items which were said to be thousands of NP profit. In reality they are 1NP or sub 1k price.
With the Kitchen Quest it started to look for items, however it said it could not find the first item. Perhaps it was unbuyable or above my total cost, if so it needs a different error message.
All in all though, the 4 bots are really good. Looking forward to more updates.
Ran Kitchen Quest again, Could not get accurate pricing for 'xxxxx'.
It's something worth just over 1k.
