Mate, dont give in. You dont need the best of the best, you have to start somewhere.
Im 26, I have a $460,000 mortgage(house was $515,000), I dont have kids, but I have a girlfriend and kids will come. 6 months ago I bought my first boat, it's only a 4.3metre Clark runabout tinny, it has all the gagets I need(sonar, gps, marine radio, electric motor), it has a 40hp petrol motor and is very reliable - all for $4800. I also bought a 4x4 ute to tow it at the same time for $5500. Both are very reliable. It is easy to do, you just have to put your mind to it and look for bargins. P.S I got the car off ebay! lol
