aladdins were good, nowadays they are all cheap clones that works very bad. As much as 50% of most cloned aladdins are non-working upon delivery.
About solderless ones, I have had great experiences with the Xenium S.P.ICE. Easy to install and reliable. A soldered one is preferred of course so if you know someone that can do that go for it. Or if you can get your hands on a premodified xbox with chip and a larger hdd for a decent price thats even better...
If you are getting a chip to solder you can never go wrong with any xecuter chip. 2.6Lite and upwards are great.
If any of those would be to expensive the best cheapmod around is the DuoX2. I have one of those myself and I am loving every second of it.
