I have avenger 200cc 2008 model which i am planning to sell and buy a RE Thunderbird or classic 350.

Long time back in 2008 i had planned to buy RE Thunderbird but many negative reviews about thunderbird like rusting,oil leak etc. haunted me and i went for avenger 200cc. I Rode avenger for 3 years(rusting occured on avenger within 6 months of purchase) but i am back again with planning to buy a RE bike and this time considering classic 350 also. I am going through many threads on xBhp.com and team-bhp.com and again i am seeing negative reviews(although these threads are started in 2009 and 2010 with no recent thread in 2011). Went to showroom in mumbai (thane and bhandup) and asked about the previous problems and they told me its history but still not sure if these are solved. Can any of the RE guru's tell me what problems should i expect in thunderbird and classic 350? or i should stick with my existing avenger. i am worried because shelling out Rs. 1,20,000 on TB and Rs. 1,23,000 classic 350 and purchasing 'N' number of problems is not the risk i want to take.

Note: for the record i ride in 60-80 speed range.
