SSTR is a shame but generally unavoidable in the current market conditions - it is hard to ignore the volume of flying you will get with RyanAir and the pay is good assuming you get the right roster.
However, paying for line-training is just plane (see what I did there?) wrong IMHO.
Is it a career (i.e. where they pay you) you are looking for or just the world's most expensive playground ride (where you pay them)?
