The 3 you listed would be the top 3 I would suggest. Only issue I have heard about with a TX200 is the weight of the gun. The R9 is a nice little rifle, mine weighs about the same as my 30-06. The 34's are a step down but still very serviceable rifles. Kind of comes down to your budget. The TX is going to be around $650, an R9 will run you about $450, and the M34 about $300. A decent scope will be another $200.
