Phil stones went up for the exact same reason you want them, to get to 102 with sun water. Even at that price they are still the cheapest way to level up. Camp them until 101/102, then camp heliodors for malison medallion until 104/106. At that point, go farm an alchemist's torque and make hexed nails until 105, hexed slops until 106, hexed coif until 107, hexed gages until 108.
When you are 108 you will either need to eat the loss with hexed doublet until you can tier it at 109, or find a smithing friend so you can spam killer's kilij until 109/110.
