I don't want to burst your bubble but you should be aware that ALL airsoft guns will break down at some stage. Some will break the first time you pull the trigger, others will last a long time even without any maintenance, but the one thing they all have in common is that they will break. Ask any (honest) retailer and they will say the same thing.

Having said that this AEG (think it's from Cybergun) is a popular gun and I have yet to hear any horror stories about it. The caveat is that all the users I know have the military version rather than the 1928 Chicago 'mob' version you have specified, but the internals are almost certainly identical. If you're just doing a bit of plinking it would be a good choice, but if you intend to skirmish with it the military version is more 'realistic', but it's entirely up to you.

most people have the 'military' version as it was the only stock thompson available for some time, up untill know you have only had expensive after market garage conversion kits ( still we do not have a version with the correct reciver/bolt but that is coming from ares )

but both version where used in the second world war by both us and british forces, the earlier version with vertical hand grip, compensator etc was produced before the us entered the war and supplied to allied forces under aid programs, when they entered the war new versions came out, the thompson was not a cheap firearm to make so the latter version ( what we called the military version hear ) are more stream lined to produce and dropped some of the features of the earlyer models

in general you looking at late early for the 'Chicago' and late for the 'military' with a leaning towards british/commonwealth forces with the Chicago although i have seen pictures of both being used right up until the end of the war

In terms of the aeg itself, the gearbox is solid and easy to work on, it takes v2/v3 parts which means spares are easily available, the barrel is a good length and the hop up unit is reliable with a large stock for plenty of battery space, out of the book i have found the cyma thompson to have lake luster rof as the motor is not the best so in the long run something you may want to upgrade including the bucking and barrel for easy cost effect performance upgrades, receiver construction is mostly metal and the construction has been improved over the TM version so it does not have a tendency to break in half at the barrel/receiver join which is a good thing

I haven't heard of many problems with them, but they're not overly common so that could simply be coincidence of numbers. Most people who buy them are collectors, or even re-enactors, so it's rare to see one heavily used.
The drum mag would be the only part that would be problematic when skirmishing, though a standard Thompson magazine does also fit, so it's not too prohibitive.

I'd highly suggest taking a look at one in person first, as they're a pig to shoulder and many find them uncomfortable in the hand. Get a feel for one in a store before splashing out.
