Miller , Hobart, Lincoln are all good quality welders you should purchase what you can afford and get local service/parts for. I went with a 130 Hobart because at the time I started looking it went on sale at a local farm store and had the quality/features I was looking for. It has done everything I have asked it to do I have no regrets. Mine has the gas rig and that really works well for items like welding wheel flares. I have also use flux core wire ( no gas ) and that works well in windy conditions and on rusty metal. Mig is quite versatile but like anything else takes practice. You have to develop the " feel " , this is knowing how long to stay in one spot along with move rate of the tip. If you are a clod with no feel/touch in your hands you may be disappointed in the results. Excellent suggestion was made on taking a welding class, this is a great way to be taught by someone that knows what they are doing and hopefully can teach
. Once you learn the skill you will be amazed what can be done with just some practice. Good luck.
