I have a chance on purchasing a ten year old osburn 2400 for around 800.00 It has the blower on it and the not so nice gold door . I've only seen pictures But was able to speak with the owner. So besides overheat or cracks in the Stove , bad welds what should I look for ? ? ? Were there any updates to the 2400 in the last ten years ? It's a 5 hour drive but if it checks out it would be Worth it . Thanks in advance for your warm comments !
