If it's more than $100 I wouldn't buy it, but I wouldn't buy the FNI either. If you plan on keeping whatever it is you buy then it makes sense to buy quality that won't be obsolete or fail in a year or two. The FNI is made to be cheap but the price isn't really cheap for what you get. I guess it depends on what your long term goals are. Fortunately with that size tank it won't be hard to light it.
